Abstract:

To solve the problem of task allocation in reconnaissance and attack on ground targets by multi-UAVs with complex constraints, the impact of multiple uncertain factors such as uncertain task execution time, target disappearance time and UAV cruise speed on the task allocation results is considered. A fuzzy chance constrained programming model for multi-UAV task allocation is constructed based on the fuzzy credibility theory, with minimization of the total cost as the optimization goal. In addition, a Multi-Strategy Integrated Grey Wolf Optimization (IMSGWO) algorithm is proposed. By introducing the adaptive control parameter adjustment strategy, adaptive inertia weight strategy, optimal learning strategy and jumping out of local optimal strategy, the search ability of the algorithm is improved while enhancing population diversity. Numerical results show that the proposed algorithm can effectively solve the problem of multi-UAV task allocation in uncertain environment.

Key words: multiple unmanned aerial vehicles, heterogeneous unmanned aerial vehicles, task allocation, uncertain environment, grey wolf optimization algorithm
